当ComponentScanning其他@SpringBootApplications时，SpringBootApplication排除 [英] SpringBootApplication exclude when ComponentScanning other @SpringBootApplications

问题描述

我在防止Spring Boot自动配置某些类（在此示例中为SolrAutoConfiguration）时遇到了一些困难。为了说明我设置了一个简化的例子：

I'm having some difficulty preventing Spring Boot from auto configuring some classes (in this example: SolrAutoConfiguration). To illustrate I've setup a much reduced example:

https://github.com/timtebeek/componentscan-exclusions

实际上有20多个内部 @SpringBootApplication 项目，每个项目都有自己的依赖项。 （不理想/不是我的想法，但现在很难离开。）

In reality there's some 20+ internal @SpringBootApplication projects, each with their own dependencies coming together. (Not ideal / not my idea, but hard to move away from now.)

问题出现是因为多个子项目正在使用Solr 5.2.1，但Spring Boot只是兼容4.x.在最终的应用程序中（示例中的module-b）我想在所有模块中导入所有 @SpringBootApplication 类，同时阻止 SolrAutoConfiguration 来自运行：

The problem arises because multiple subprojects are using Solr 5.2.1, but Spring Boot is only compatible with 4.x. In the final application (module-b in the example) I want to import all @SpringBootApplication classes across all my modules, while preventing SolrAutoConfiguration from running:

@ComponentScan("project") // Broad scan across all company jars
@SpringBootApplication(exclude = { SolrAutoConfiguration.class }) // Failing exclude
public class ModuleBApp {
    public static void main(final String[] args) {
        SpringApplication.run(ModuleBApp.class, args);
    }
}

这失败了，因为任何<$ c $的实例c> @SpringBootApplication 通过 @ComponentScan 获取而没有特定排除，仍然加载 SolrAutoConfiguration 。

This fails, because any instance of @SpringBootApplication picked up through the @ComponentScan without the specific exclude, still loads SolrAutoConfiguration.

在组合多个 @SpringBootApplication 类时，如何正确排除自动配置类？

What can I do to properly exclude a auto configuration class when combining multiple @SpringBootApplication classes?

我已经尝试在我的最终 @SpringBootApplication excludeFilters >，但尚未找到解决方案。

I've already tried to work with excludeFilters on my final @SpringBootApplication, but that hasn't yet lead to a solution.

推荐答案

Spring Boot 1.3.0.M3引入了排除自动配置的功能使用属性：
https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-1.3.0-M3-Release-Notes

Spring Boot 1.3.0.M3 introduced functionality to exclude autoconfiguration using properties: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-1.3.0-M3-Release-Notes

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.solr.SolrAutoConfiguration

请注意，它应该如发行说明中所述 spring.autoconfigure.exclude ，而不是排除。

Note that it should say spring.autoconfigure.exclude, not excludes as in the release notes.

这有助于防止Spring Boot fr om在存在多个 @EnableAutoConfiguration / @SpringBootApplication 注释的情况下加载autoconfig类。

This helps prevent Spring Boot from loading autoconfig classes in the presence of multiple @EnableAutoConfiguration/@SpringBootApplication annotations.
